Task 36 The figure shows a scheme for pumping water with a pump M into a container with an overpressure P0. The liquid level in the container is H0. Water is supplied by a pump through a pipe L with a diameter d = 5 cm.The loss coefficient along the length of the pipeline λ = 0.02. Local pressure losses during rotation ξp = 1 and sudden expansion ξp = 1. The hydraulic characteristic of the pipeline is quadratic, the pressure characteristic of the pump H(Q) = A – B *Q2. The ambient pressure is atmospheric. The water density is 1000 kg / m3. Determine the volume flow rate of water

H0 = 7.2 m, Po = 22 kPa, L = 13m, A = 15m, B = 1.6 * 105 s / m2
